Application and September 23.1929. Serial No. 394,492.

This invention relates to improvements in item counting mechanism forlisting machines. r

The item counting mechanism of the present invention is applied to alisting machine of the general type shown and described in J ohantgenPatent No. 1,336,840, issued April 13, 1920, although the item countingdevice might be applied to listing or adding machines of otherconstruction.

The listing machine with which the present invention is associated isone which is designed primarily for use in the listing and recording ofa group of items constituting the purchases of a single customer, insuch form that a record slip thereof may be torn off and delivered tothe customer as a record of the transaction.

The machine lists several items in column form, and upon the depressionof the total key and the operation of the handle, takes a total thereof,which results in a clearing of the machine for subsequent transactions.

The features of the present invention are designed to make a count ofthe number of items thus listed and record a total thereof, so that therecord slip will thus display in ad joining columns not only the numberof items involved but the aggregate of the amounts represented by suchitems.

In providing the item counting mechanism, use is made of stock parts,such as rack bars, hammer devices, accumulating, carrying and totalizingmechanisms, which parts are identical, or substantially so, with" thoseregularly employed in the item listing section of the machine, so thatmachines of the type already constructed can, without substantialreorganization and with the addition mainly of stock ,parts, be providedwith the supplemental item counting and totaling mechanism whichconstitutes the present invention.

Provision is also made for the unlocking and releasingof the itemcounting rack bar bythe depression of an key in the several ordersconstituting the item series and provision is also made for the releaseof the item counting'rack bar b the depression of the total key, sothat, wit out special adjustment, the counting and totaling of items wil proceed in re lar order as the items are listed, accumu ated andtotaled in the regular operation of the machine.

Further objects anddetails of the invention will appear from adescription thereof, in conjunction with the accompanying drawings,wherein,

The machine as a whole closel construction and arran ment of parts shownand described in the 1,336,840, but since a general description isnecessary in order to gain a full understanding of the mechanismsinvolved in the present invention, the structure of the machine will bebriefly described as follows:

The machine comprises a main or body frame, which includes side platesand a follows the ohantgen Patent No.

top plate or keyboard 21 through which extend the key stems 22 of itemkeys 23. As shown, four orders of item keys are employed, although thenumber of orders may obviously be increased to any desired limit.

The key stems of a row of keys constituting a single order are arrangedin step formation, and the lower ends of the stems are entered throughand guided within a stepped cross plate 24, each of the key stems beingsurrounded by a coil spring 25 adapted to restore the key to elevatedposition after it has been released from depression.

I The lower ends of the row of keys constituting a single orderco-operate with a stepped rack bar 26 provided with shoulders so locatedthat each will coact only with its own particular key, so that when aselected key within a single order is depressed it will constitute astop for arresting the forward movement of the rack bars at theparticular point constituting a representation of the numeralrepresented by the key.

Each order within the limits of the machine is provided for by the useof a row of keys and a rack bar coacting together in the mannerindicated. Each of the rack bars terminates at its forward end in a rowof upwardly projecting rack teeth 27, the several rack teeth in thedifferent orders 00- acting with spurpinions 28 which constitute theaccumulating wheels and which are each associated with a disk 29provided on its periphery with visible numerals corresponding to theteeth of the associated accumulating wheel. I

The accumulating section occupies the forward portion of the machineimmediately in front of the keyboard, and this section of the machine isin all substantial respects like that shown in the Johantgen Patent No.1,306,112 and the J ohantgen Patent No. 1,336,840, but may be brieflydescribed as follows:

The several accumulating wheels composing the series are freely mountedupon a fixed shaft 30, the ends of which are mounted between S-shapedplates 31, which are connected by an upper cross bar 32 and a lowercross bar 33, and constitute a frame or cradle which rocks upon a crossrod 34, the ends of which are mounted within L-shaped brackets 35 eachcomprising a forwardly extending leg and an upwardly extending leg, asindicated in Figs. 3, 4 and 5.

The forward legs are pivoted at their forward ends upon studs 36, sothat the brackets, in conjunction, constitute a rocking frame whichcarries the cradle, which latter is also capable of a rocking movementupon the cross rod 34. v

The brackets 35 are rocked downwardly and forwardly against the tensionof a spring 37, and the upper arms of the brackets serve to journal ashaft 38 which constitutes a POI- tion of the carrying mechanism.

The shaft 38 serves as a mounting for a plurality of detents 39, one foreach numeral order, with the exception of units, and each of the detentsis bent to afford on one side a toothed pawl 40 the teeth of which areadapted to mesh with the teeth of the associated accumulating wheel, sothat when the arts are adjusted for carrying, the detent Wlll be rockedto introduce a movement'into the associated accumulating wheel.

Each detent also includes an arm 41 which terminates in a forwardlextending latch finger 42 and a downwar ly extending stop finger 43, sodisposed that all of the stop fingers will engage a universal liftingbar 44, which is carried between swinging arms 45, the upper ends ofwhich are journaled upon the ends of the shaft 38 which carries thedetents, the relation of the parts being such that when the universallifting bar 44 is swung upwardly and rearwardly it will swing all of thedetents in unison, thereb elevating all of the latch fingers 42, whiclifting operation, however, occurs while the toother pawls 40 are out ofmesh with the corresponding accumulating wheels, as in Fig. 12, so thatthis lifting action will not at this stage eflect carrying.

Each of the detents 39 is drawn downwardly and forwardly by a coilspring 46 which holds the arm 43 in close enga ement with the universallifting bar 44. e toothed pawls 40, during each cycle of movement of thehandle, are first thrown out of mesh with the corresponding accumulatingwheels, and afterwards thrown into mesh therewith, which latter is thenormal or restored position of the parts. swinging or rocking movementimparted to the bracket arms 35 which rock on the studs 36, therebyswinging the upper ends of the brackets first forwardly and thenrearwardly to efi'ect the successive dimngaging and engaging of thetoothed dogs with the accumulat ng wheels.

Each of the accumulating wheels has associated therewith a cam 47 whichrotates by successive steps with its associated accumulating wheel in acounter-clockwise direction, as viewed in Fig. 12.

Each cam on its tenth step of movement will encounter a latch keeper 48which is in the form of a bent finger depending from an enlargedring-shaped head 49, which is pivotally mounted upon a cross rod 50which connects the upper arms of the S-shaped plates 31 wh ch carry theaccumulating wheels. These S-shaped plates 31 and the cross connectingbars 32 and 33 and the rod 50 may in conjunction be appropriatelyreferred to as the accumulator frame.

Each latch keeper is drawn forwardly by the action of a spring 51, theforward end of each spring being connected to a tongue 52 upwardlyextending from a trip dog 53 pro- This action is effected by a.

' respective accumulating wheelsywith the revided with a re'arwardlyextending arm 54 having formed at its rear end an inner shoulder 55 andan outer shoulder 56, as indicated in Figs. Hand 12. With the parts innormal position, the latch keeper will engage the inner or forwardshoulder 55, and'when so held it will be in position to engage with and.

- mit a return movement of the detents thus unrestrained at a time whenthe toothed dogs are thrown into meshing relation with the correspondingaccumulating wheels, so that the accumulating wheels thus engaged willbe moved one step in carrying. 7

After the trip dog 53 hasfunctioned to restrain the latch keeper in themanner stated, it will be ultimately restored to normal or elevatedposition by the action of a finger 57 on the associated detent 39, whichwhen restoring is brought into contact with the tail portion 58 of thetrip dog, which contact serves to lift the arm 54 sufiiciently to permitthe latch keeper to restore to theposition of contact with the shoulder55, as indicated in Fig. 11.

This cycle of operations involved in carrying is thus initiated by thecam 47 which swzngs back the latch keeper provided to control the nexthigher order accumulating wheel, so that the latch keeper will fail torestrain the latch finger 42 when momentarily elevated by the action ofthe universal cross bar 44.

With the return of the cross bar, those latch fingers which areunlatched will swin downwardly, and at the same instant alf of thetoothed dogs will swing into mesh with the salt that those; dogs whichare moved by the swinging-back of the unlatched detents will throw acarry into the next higher order ac- I cumulating wheel.

During the accumulation of items, the re; spective accumulating wheelswill be throwninto mesh with the movable rack bars dur-' ing the returnmovement of the operating handle, while in total taking the parts willcome into mesh on the forward movement of the handle. This is efl'ectedby a straight line up and down movement of the accumulating frame whichrocks on the cross rod 34 and at the same time is restrained in asubstantially vertical path by the action of studs 59 which move withinslots 60 in bracket arms 61 forwardly extending from the main or bog;frame of the machine.

ovement is imparted to the L-shaped bracket arms 35 which pivot on thecross rod 36 through the action of a link 62 on the left side. of themachine, which link is provided with a roller 63 traveling in an arcuateslot 64 in a segment 65, which is pivoted upon a stud 66 and is actuatedby a draw bar 67 which derives its movement from connections actuated bythe movements of the handle.

The handle 68, which is located on the right hand sideof the machine, ismounted upon a main power shaft 69 extending transversely through themachine near the forward end thereof.

The power shaft is provided with a crank I arm 70 which actuates linkage71, which need not be described in detail and which in turn serves toactuate a segment 72 on the right hand end of a secondary shaft 73,which shaft on the left hand side of the machine carries a disk 74provided with outstanding studs 75 and 76, which are spanned by anangular bridge plate 77.

The draw bar 67 has pivoted thereto an upper arm 78 and a lower arm 79(see Figs. 3 and 4). With the parts in the restored or normal positionshown in Fig. 3, the upper arm 78 will be elevated sufliciently to celarthe stud 76 when the disk 74 is rotated in a clockwise direction by theforward pull of the handle; while during the same adjustment the rearend of the lower arm 79 will occupy a position which permits the stud 76to engage and swing past the end of the arm 79 during the forward handlepull, until the stud occupies the lowermost position. On the returnmovement of the handle, the stud 7 6, moving in a counter-clockwisedirection,

will engage the rear end of the arm 79, and through it impart a forwardthrust to the bar 67, thereby swinging the segment 65 on its pivotalmounting 66, which through the roller 63 imparts a forward movement tothe link 62, thereby rocking the cradle afforded by the swinging arms 35which results in a lowering movement in the bank of accumulating wheelsinto engagement with the respective racks, so that on the restorationofthe racks a rotative movement will be thrown into each accumulatingwheel commensurate with the forward movement permitted to the racks inthe several orders.

As the handle is restored, the stud 76 as it returns to its uppermostposition will engage a detent 80' pivoted on the forward end of. thedraw bar 67 and draw back the same, thereby operating the segment 65 andparts controlled thereby, with the result that the bank of accumulatingwheels will be/ lifted above the path of movement of the rack bars inpreparation for the next succeeding operation.

In total taking, a total key 81 is depressed, which key ismounted upon astem 82 provided with a stop finger 83, which underlies the upper ivotedarm 78. As the finger 83 is lowered, t eupper arm 78 will be drawn downby the action of a coil spring 84 which connects the arms 78 and 79.

The upper arm 78 is provided with an end hook 85 and an intermediateshoulder 86, and when the arm is lowered the shoulder 86 will lie inposition to be engaged by the stud 76 as the handle is drawn forwardly,with the result that in total taking the operations necessary to lowerthe accumulating wheels into engagement with the rack bars will occur atthe beginning of the handle stroke, so that the bars will move forwardlyin varying degree until the several accumulating wheels have in eachinstance been restored to the zero point, which in each instanceconstitutes the degree of movement allowed to each rack bar in therecording of a total.

With the parts in total taking position, the hook 85 will lie inposition to permit the stud 75 to swing under the hook and engage withit on the forward handle pull, so that restoration of the partswill beeffected by such engagement as the stud swings backwardly and downwardlyon the return movement of the handle. (See Fig. 4.)

Each rack bar is under the tension of a spring 87 which tends to draw itforwardly to its extreme limit of movement, but all of the rack bars arenormally held in rearmost position by the action of a universal bar 88which operates through aligned slots 89 in the respective rack bars, sothat, as the restoring bar is drawn forward, the respective rack bars,if unlocked, will move forwardly until arrested by the depression of akey in the corresponding order, in a manner well understood in theadding machine art.

The restoring bar is actuated by means of pivoted levers 90 on each sideof the machine, each of which levers is slotted at its free end 91 toreceive a roller 92 on the corresponding end of the universal restoringbar, so that, as the levers 90 are oscillated, the re storing bar willbe moved on each handle op eration to the full extent of its range ofoperations. The levers 90 are actuated by cranks 93, one at each end ofthe main power shaft 69, which are provided with rollers engagingarcuately configured arms 94 on the levers 90, so that the latter willswing or oscillate in unison as the handle is pulled and re stored.

Each of the rack bars is of channel shaped formation throughout its bodyportion, as indicated in Figs. 6, 7 and 8, and provision is made fornormally locking all of the rack bars against release, save by thedepression of a key in the corresponding order or by the depression ofthe total key. This is effected in the manner shown in the JohantgenPatent, No. 1,336,840, by the provision, for each order group of keys,of'a rack lock plate 95 in the form of a gate provided at each end witha pintle 96 which constitute pivots, permitting the rack lock plates toswing laterally through the depression of a keg in the correspondingorder.

ach rack lock plate, at its rear end, is provided with a dependingfinger 97, which normally, as in Fig. 6, occupies a substantiallyvertical position and engages with a notch formed in the rear end of thecorresponding rack bar.

Each of the key stems 22 is provided on its edge with an upper notch 98and a lower notch 99, with an intervening lug 100. The swinging racklock plate is provided, along its lower edge with inturned tongues 101,one for each of the notched key stems. As a key is depressed, the lug100 will engage and cam aside the associated tongue 101', therebyswinging the rack lock plate on its pivotal mounting and causing thefinger 97 to release the corresponding rack bar, and this will occurirrespective ofwhich of the item keys in a single order is depressed.The keys are held in depressed position by swingmg key lock plates 102similar to the rack c6c3k plates, and similarly hinged on pintles Eachkey lock plate is provided with a series of inwardly extending tongues104. VVIth the key stems elevated, these tongues will normally liewithin the lowermost notches 99, but as the key is depressed the lug 100will cam aside the associated tongue until the key has been depressedsufficiently to permit the tongue to enter the upper notch 98 whichlooks the key in the depressed position. The key lock plate and the racklock plate are held together by a bow spring 105, or other suitabledevice, so that they can only be spread apart by positive action.

The construction of these features is in all respects similar to thatshown in the J ohantgen Patent, No. 1,336,840, and further description1s deemed unnecessary, nor is it deemed necessary to describe theconstruction and arrangement of the type bars and printing mechanism,which of course are connected and associated with the rack bars, so thatin each instance each type bar will be moved in a degree commensuratewith the movement of the rack bar to bring the proper type figure to theprinting line.

In total taking, it is necessary to unlock all of the keys and rackbars, and to this end universal mechanism is provided which will now bedescribed. 7 a

At the rear of the machine is located a release bar 106, which is in theform of a bail provided at its right hand end (as viewed from the front)with an arm 107 pivoted to a stud 108. The arm has pivoted thereto a camsegment 109 provided with a finger 109 which bears upon the end of thestud 108, which cam segment on the return movement of the handle isengaged by a roller 110 carried by a segment plate 111 mounted on thesecondary shaft 73, the parts being so disposed that on the forwardmovement of the handle the roller 110 will ride under the lower edge ofthe cam segment and lift the same, causing the finger 109 to lift awayfrom the end of the stud 108, but on the return movement the roller willengage the forward edge of the cam segment and cause the finger 109 tofulcrum on the stud 108, as indicated in dotted lines in Fig. 2, therebylifting the rear end of the cam segmentand imparting an upward liftingmovement to the bail shaped universal release bar.

The universal release bar at its left hand end (as viewed from thefront) is provided with a forwardly extending arm 112 pivoted to a stud113, which arm is provided with a forward extension 114 (see Figs. 3 and4), which is so disposed as to occupy a position immediately below afinger 115 outstanding from the stem of the total key 81, so that as thetotal key-is depressed the extension 114 will be carried down and therear end of the arm 112 elevated, thereby lifting the universal releasebar independently of the action of the handle.

The universal release bar is provided with upstandin teeth or elevations116, which as shown in ig. 7 normally in each instance occupy a positionbetween the lower edges of i the key lock plate and the rack lock plateof the corresponding order, but without serving to spread the plates.When the universal release bar is lifted, either by the normal operationof the handle in restoring or by the depression of the total key, theteeth or elevations 116 will be elevated, as shown in Fig. 7, therebysimultaneously separating the key lock bars and rack lock bars of allthe orders, so that all of the rack bars will be unlocked and all of theitem keys restored to elevated position.

In the normal handle operation this elevation of the universal releasear occurs toward the end of the stroke and is but momentary, the bardropping back to its lowermost position at the end the handle stroke. Intotal taking, however, the depression of the total key lifts the bar andholds it ele vated throughout the entire operation, which is necessaryin order to unlock all the rack bars which may be involved in theclearing.

stitutes the subject matter of the present invention.

I tam counting mechanism In addition to the rack bars and accumuof atotal of the number of items listed and' recorded in the operation ofthe machine.

As shown in Figs. 6 and 7, the machine is equipped with item countingrack bars 117 and 118, the former of which is released and registers asingle unit with each significant operation of the handle. The rack bar118 and accumulating and carrying mechanism associated therewith areprovided to afford a reserve in the counting of more than nine items.The rack bar 117 is normally locked against advancing to the firstposition (numeral 1) by a stop finger 119, which depends from the end ofa slide bar 120 mounted upon the universal release bar 106.

The slide bar provided with slots 121 which receive pins 122, so that ithas a limited transverse movement along the bar and also partakes of thelifting movement of said release bar when the same is actuated. Theslide bar is provided along its lower edge with inturned fingers123,.one for each order, which lie laterally adjacent to the fingers 97which depend from the respective rack lock plates 95, and a spring 124serves to hold the slide plate 120 in the normal or left hand position,as indicated in Fig. 6.. The result of this arrangement is that wheneveran item key, in whatsoever order, is depressed, the swinging movement ofthe corresponding finger 97 will impart a sliding movement to the slidebar 120, and thus displace the stop finger 119 toward the right, in Fig.6, thereby unlocking the item count rack bar 117, which is thuspermitted to move forwardly one step when the handle is pulled and theuniversal restoring bar 88 actuated. In like manner, when the total keyis depressed, it will elevate the bar 106 and with it the stop finger119, so that in this instance also the item count rack bar 117 will bereleased, so that it will be free to travel to the extent required inrecording a total of the number of items listed since a previousclearing of the machine.

In order to permit the rack bar 117 to advance a single step with therecording of each significent item, ,a lock plate95 is provided which issimilar in all respects to the rack lock plate 95 previously described,except for the fact that a finger 97 corresponding to the finger 97 isnotched to afford free -movement of one space to the rack bar 117, afterwhich additional movement of the bar 117 is prevented. The reserve rackbar 118 will be normally locked in its rearmost position by its finger97 as in the case of the rack bars constituting the item accumulatinggroup.

In view of the fact that the rack lock plates which coact with the rackbars 117 and 118 are not associated with depressible keys, it is evidentthat the racks 117 and 118 will be restrained against full forwardmovement so long as the respective lock plates maintain their normalposition, and since these two rack lock lates will only be moved whenthe release ar is lifted, which occurs durin total taking, it is evidentthat in the tota taking operation the bars 117 and 118 will be free totravel forward to the degree permitted by the respective itemaccumulating wheels, so that a total will be taken out of theseaccumulators concurrently with the total taken from the item accumulatorwheels.

The item count rack bars 117 and 118 are connected with printing devices125 similar in all respects to the printing devices actuated by the itemrack bars as shown in J ohantgen Patent No. 1,336,840, so that it is notdeemed necessary to describe in detail the manner in which the itemcount is printed. Nor is it necessary to describe the manner in whichthe paper strip is fed or the platen is actuated in line spacing.

O pemtzon A brief rsum of the operation is as follows:

An item is set up by the depression of the item keys in the variousorders. The depression of the item keys by the spreading of the key lockplates and rack lock plates serves to lock the keys in the depressedposition and also to unlock the adding rack bars in the various ordersrepresented in the item. The forward travel of the unlocked adding rackbars, however, is at this stage prevented by the universal restoring bar88.

The first item key depressed, in whatsoever order, will, through theswinging movement imparted to the associated rack lock plate,

impart a sliding movement to the slide bar 120, which displaces the stopfinger 119 from lockin relation with the item adding rack bar 11 which,however, at this stage, is also restrained by the universal restoringbar 88. After the first item has been fully set up, the handle is drawnforward, which carries with it the restoring bar, thereby allowing theitem racks to move forward until stopped in various positions by contactwith the depressed item keys, and also allows the item count rack bar117 to move forward one space, where it is stopped by the finger 97 ofthe associated rack lock plate 95. The reserve rack bar 118, however, ispermittedno movement whatever, since the rack lock bar with which it isassociated is unaffected by the depremion of the item keys.

After the handle has been drawn forward and the several rack barsappropriately positioned, the handle will be released, which as abovedescribed.

causes all of the accumulating wheels, including the item count wheels,to be lowered into meshing relation with the associated racks, and asthe return movement continues, the wheels will be rotated in eachinstance to a degree commensurate with the movements imparted to therespective racks, and the type bars will be lifted, in varying degrees,to the printing line, and the record imprinted upon the paper strip.During this return operation, the item count wheel associated with therack 117 will be rotated one step and the numeral 1 imprinted in alignedrelation with the item represented, and the single movement of the itemcount accumulator wheel will remain stored up in that wheel. Assubsequent items are listed and printed, like operations will recur, thefigure 1 being imprinted by the item count printing mechanism in alignedrelation with each item, and the number of items involved will beprogressively stored up in the item count accumulator.

When it is desired to take a total, the total key will be depressed,which in this instance actuates all of the rack lock plates, so that allof the rack bars, including the item count rack bars, will be free topartake in the total operation, and at the same time the depression ofthe total key sets the mechanism required in reversing the order ofoperations, so that, on the forward movement of the handle, therespective racks will be enmeshed with the associated accumulatorwheels, and in each instance advance until the enmeshed accumulatorwheel is restored to zero, which clears the machine and results in theprinting of the total of the items and an alined imprint of the total ofthe number of items.

It will, of course, be understood that the reserve accumulatingmechanism associated with the reserve item count rack bar 118 will comeinto play only in event that the number of items listed in the groupexceeds 9, in which case the excess items will be carried over into thereserve accumulating wheel, so that in this case, in the totalingoperation, the rack bar 118 will be permitted an advance movement as itsassociated accumulator wheel is restored to zero.

Although the rack lock plate 95 does not coact with the depressible itemkeys, and although the functioning of the machine does not require thatit be of full length and of a configuration similar to that of theracklock plates 95, convenience and economy in quantity productionindicate the desirability of utilizing one of the standard or stock racklock plates, slightly modifying by notching the finger 97, and suchpractice has been observed in the construction of the machine Althoughthe operation of the machine requires a momentary lifting of the releasebar 106 toward the end of each handle stroke,

spread all of the key lock plates and rack a storation of the keys andthe relocking of the racks, this action is timed to occur immediatelafter the restoring bar 88 has reached t e limit of its rearwardmovement, so that the momentary unlockin of the racks at this stage willnot permit any uncontrolled advance' movement of any of the racks,including the item count racks 117 and 118, so that such a momentaryactuation of the key lock plates and rack lock plates will beineffective to disturb the accumulation either of items or totals in theitem listing group and item counting group of mechamsms.

The invention is one which may be readily applied to and introduced intomachines of standard construction without re-organization of themechanisms, and with but. slight addition to the standard construction,so that the machines of standard form may be provided with the itemcounting features,

' swung to unlock the associate universal releasing bar extendingtransversewith but slight additional expense, .and when so equipped willcount and total the number of items as an incident to the regularlisting operation.

Although the invention has been described in detail, and although, asshown, it has been applied to a standard listing machine of thecharacter shown and described in the J ohantgen Patent, No. 1,336,840,it will be understood that it is not the intention to limit itsapplication to machines of-this precise character, since it may beotherwise applied as occaslon may arise.
